Retrieval-Masters Creditors Bureau Inc., whose business was blamed for a large-scale data breach that affected millions of Quest Diagnostics Inc. customers, filed for chapter 11 protection, citing fallout from the security issue, Bloomberg News reported. The company, which collects patient receivables for medical labs under the name American Medical Collection Agency, listed assets and liabilities of as much as $10 million in its bankruptcy petition filed in the Southern District of New York. It’s aiming to liquidate, the company said. Court documents cited a breach discovered in March that affected millions of people, including customers of Quest Diagnostics and Laboratory Corporation of America. Soon after, Quest, LabCorp, Conduent Inc. and CareCentrix Inc. -- American Medical’s four largest clients -- stopped doing business with the company, leading to the bankruptcy filing, according to court papers.
